[opendingux] Handy320 (lynx)

Hi, everybody.

--------------------------------------------
Handy320 v0.1 for Dingux and OpenDingux
--------------------------------------------

Based on:
Handy/SDL 0.5 (c) 2004 SDLemu team
Handy 0.95 (c) 2004 K. Wilkins
Gui browser is mostly copy-pasted from gpSP by Exophaze
icon is from coccijoe's HandyOD

What's new compared to Handy/SDL 0.5
- Simple gui with rom browser is added
- Load/save states are working
- Two image scalers: simple2x and fullscreen
- Better synchronizing and better sound quality

PACKAGE
There are 2 binaries in the archive,
handy320-od.dge - for OpenDingux (Dingoo A320)
handy320.dge - for legacy Dingux (Dingoo A380/320e, Ritmix rzx50)

INSTALL
Copy either handy320.dge or handy320-od.dge to some dir on your sd-card or inner flash-memory.
Find real lynxboot.img somewhere in the internet (Google is your friend) and put it in the same directory.
Don't forget to overclock to 420 MHz if you want more speed in heavy games like Batman Returns or Crystal Caves II.

COMPATIBILITY
Handy320 supports Dingoo a320, a380 and Ritmix rzx50. Three fullscreen modes could be used:
320x240, 400x240 and 480x272 They are detected automatically, you don't have to worry about them.

Roms should be either *.lnx or *.zip. Yes, zipped roms are supported.
